Lost connexion with Bluetooth device

fabien · July 31, 2025, 6:25am

Hello

I paired a Firestick 4K remote. It works well but after a while i have a message on my TV set that my remote is disconnected then reconnected and so on. Very annoying. At the end, the remote cannot control because the entity is offline. The original cheap remote is working well.

What’s wrong?

Connect and disconnect is normal behaviour and can only be changed with the REST API. This connecting and disconnecting does not mean that the entity is offline and cannot be controlled anymore. Every time you press a button it will be reconnected.

Thanks Ralf.

I understand that it’s the normal behavior but it’s annoying to have a message on TV set that the connection is lost.

What’s the cons to change the behavior with API rest? How to do that?

I am sure Ralf will come back on how to change the Bluetooth settings in the API.

Alternatively, I am wondering if there is a way to suppress notifications on the Fire TV stick.

Here is a doc for the different modes:

github.com/unfoldedcircle/core-api

doc/bt/suspend_behaviour.md

main

# BT suspend / wakeup patterns

When the remote goes into deep sleep mode, the Bluetooth controller is put to sleep and re-initialized at wakeup.
- Some devices will show a disconnect & connect message or popup when the remote wakes up.
- Different sleep behaviour can only be configured with the REST Core-API at the moment.
- Default suspend actions if not defined (empty array): disable advertisements, then put BT controller to sleep
- Default wakeup actions if not defined (empty array): restart BT controller

```shell
curl --location --request PATCH 'http://$IP/api/cfg/bt' \
--header 'Content-Type: application/json' \
--user 'web-configurator:$PIN' \
--data '{
    "suspend_actions": ["DISABLE_ADVERTISEMENTS", "SLEEP"],
    "wakeup_actions": ["RESTART"]
}'
```

I hardly use BlueTooth. Perhaps another user can say more.

I just remembered that I played around with this a few months ago based on the information in the link in Ralf‘s post above. Maybe the below on discord is helpful:

Hello,
i send the curl command with BEST EFFORT actions but no effect. Must i reboot the remote after?
If yes, i did not find where the reboot is. Sorry i am a newbie

HarmonyFan · August 1, 2025, 7:35am

I think yes to reboot but I am no BlueTooth fan. Reboot is a bit hidden.

In setting, development, preview features is a reboot button on the bottom.

I would certainly recommend a reboot of the remote. The quickest way is to long press the power button when on the home page of the remote.

You can check the bluetooth settings in the API (in the cfg/bt section). If the remote is set to best effort you should see the following somewhere in the settings:

"suspend_actions": ["NONE"],
  "wakeup_actions": ["NONE"]

I come back with no good news. I have some disconnections, i don’t know why. Maybe a IP adress issue?

Here my log:

Bluetooth does not care about your IP. Disconnections and reconnects are normal unless you change it with the rest API. I am not sure if it is connected but I always use prevent sleep in all activities and did not have a disconnect today.

Hello

how can i check BT settings? A special curl command?

Thanks

It is in rest API /cfg/btw which is explained here

github.com/unfoldedcircle/core-api

core-api/rest/README.md

main

# Unfolded Circle Remote REST Core-API

The UCR REST Core-API is defined with [OpenAPI](https://www.openapis.org/).

You can use the online [Swagger Editor](https://editor.swagger.io/) to load and browse the specification or use your
favorite IDE with OpenAPI support (e.g. IntelliJ or Visual Studio Code).

- [OpenAPI YAML definition](UCR-core-openapi.yaml).
  - ℹ️ This is a bundled YAML file generated from individual definitions.
  - Most OpenAPI tools only work with a single file.
  - We might publish the original definitions at a later time.
- See [/doc folder](../../doc/README.md) for further API documentation and information.

## Postman Collection

For explorative API testing the `remote-core_rest-api.postman_collection.json` collection can be imported into
[Postman](https://www.postman.com/). It contains pre-defined requests and some helper scripts to propagate generated
identifier keys to simplify common tasks.

Postman also supports [importing OpenAPI definitions](https://learning.postman.com/docs/integrations/available-integrations/working-with-openAPI/).

Somewhere Markus explained what settings are possible but I do not find it anymore.

You must be a lot younger your memory seems to work better than mine.
